Mike:
It must have been the fact that your watch is the rarest of the rare with the optional extend stem winder option(see your closeup pics). This indeed places your (ex)watch in the upper atmosphere of collectibles. I have never even seen that model in the real before but heard many rumors to its existance. A mighty "way to go" for you. Question: What is the history of this magnificant piece? Where did you find it and why, oh why, did you offer it up for sale?

PS-In the future, web link addresses can be placed in the "Optional Link URL" space below the message body. That way we can just click on the link and not have to cut and paste. This will increase the access time to all those exciting ebay items before the drool hits the keyboard.
